Appiieation med February 1, 190e. serial No. 475,366. f

To all to/wm t may concern: i i y Be it known that I, HnNRrI-I. Mairena a citizen ofthe United States, and residing at Claremont, in the county of Sullivan and State of New Hampshire, have `invented an Improvement in Stoneworking-Machines, of which the followingdescription, in connec tion with vthe yaccompanying drawings, is a specification, like .letterson the drawings representing likefparts.

My invention relates to "stone" working machines, being more particularly, though not exclusively, intended for the improvement inthe eiiiciency of power-driven truck channelers or the like. A n y My invention will `be bestunderstoodfby reference to the following description when taken in connection with thevaccompanying' illustration of one Specilic embodiment thereof, while its scope will kloe more par-y ticularly pointed out inthe appended claims. f

Referring to the drawingsandto the eme bodiment of my `invention therein shown, I have disclosed. ,for illustrative purposes a common form of ,track channeler having usual features of construction which maybe briefly referred to asl follows. f The channelery is provided with a main frame orcarriage 1 mounted upon ythe usual truck wheels 2, the latter adapted to track upon the rails 3 ordinarily laid upon the quarry bottom.` In the particular machine shown the truck is propelled along the trackway under; its ownpoweigfthe motive means` therefor being herein embodied in a truck driving engine L to which pressure fluid, preferably in f the form of` compressed air or steam, is led through the feed pipe 5.,;

'For driving the truck, power is trans-l` mitted fromfthe engine through the trans` versetransmission shaft 6 to the longitudinal driving shaft 7 near theopposite side of i the truck Iby power transmission mechanism,

which will ybe more` yfully described. 'Ihe` driving shaft 7 is mounted in bearings 8 upon the carriage and is provided at each fend with worms 9` meshing with underlying worm gears 10, the latter liXedly secured f eachj uponone of the aXlesll, which latter act to drive the truck wheels 2 secured at the end thereof;

As is usual in this class of apparatus, the

cutting kappliances are shown as mounted at the active or cutting side of the truck and comprise the tool or gang of tools l2 secured i to the crosshead y13 and piston rod 14 andr adaptedto be rapidly reciprocated by `the actuating unit 15, herein in the form of a pressure fluid engine to which compressed air or steam is supplied from any suitable source byv connections not herein shown. y

For the guidance of theA cross lheads there are provided crosshead guides 16 which, to-

gether with the engine cylindeiggare united i into a unitary frame mounted yfor sliding adjustment upon suitablel giiideways 17 formed yon the uprigh-t standard 18, the ,latterl se-k cured at the side of the truck. The Sliding frame is provided as usual with gibs 19 which overlie the backy of the standard guideways so that the entire frame, with the tools and their actuating devices, may be adthe work.

i justably 'advanced toward or retracted from4 i a i The standard at its lower rearside ispro-fy vided with one or moreboXes or brackets 20 which are-shaped to lit the longitudinal.v

trunnion shaft 21, the latter secured at itsv i ends-by the cap pieces 22 to the frame or carriage. The standard may be clamped rigidly to the trunnion shaft at any desired inclination, or at :either end thereof, byl

means of the U-shaped clamping bolts23 and the clamping nuts 241.V The standard may be adjusted to different inclinations by;

loosening thefclampingbolts and altering the position and inclination ofthe standard,f

as desired-one or more lateral, brace rods 25 and rear brace rods 26 being employed as usual to brace orstay the upper part of the standard while the machine is cutting.

During thek operation of the machine the vchanneler 'is advanced along the trackway,

theV tools acting to cut achannel groove of 1 member or nut 31, which is rigidly secured to a part of the engine cylinder castingr so l that the turning of the screw in onel direction or the other retracts oradvances the cylinderframe. For turning the screw the @latter has secured to its upper end above the collar 29 the beveled'gear32 which meshes with the smaller beveled pinion 33 on the short shaft 34, the latter carrying on its outer end the sprocket wheel 35 adapted to' be turned by the sprocket chain 86. The shaft 34 may be manually turned Ato feed the tools by means` of the handle yprovided on the sprocket wheel, but, for feeding by power the chain passes down to the carriage 'frame wherefit is engaged by the driving' sprocket wheel 37 to which power-actuated turning movement may be imparted for lowering or raising thev tools,l such movement being herein transmitted thereto from the engine 4 on the transmissionfshaft 6 through power 'transmission gearing to be more fully described. f

Referring to the power; transmission devices interposed between the engine and the truck-driving mechanism onv the one hand and the tool feeding mechanism on the other, reference may be had to Fig. 4 and also more particularly to Fig. V6. From this tions, one'of which is effective toy drive the truck in one direction, another in the opit will be seen'that the transmission shaft 6' carries fiXedly secured to its vouter end the beveled gear38, the latter meshing with the two gear members 39 and 40, and acting to drive both of them at the same speed but inV opposite directions.

' Bothgear or truck-driving members 39 and 40 are mounted to rotate loosely upon the countershaft 41', but may be clutched thereto, either one at will, to turn the same in either direction and thereby turnthe pinion42 keyed to the said shaft and meshing with `the "gear 543, the latter keyed to the truck-driving shaft v7'. f 'f Any suitable form of clutching means maybe employed, vbut herein means are provided as follows;A the construction being substantially the same foreach clutch device so that one only need be described. Re-

.ferring to thegea'rumember 39, the same is provided with an outwardly'eXtended drumshaped portion 44 which is encircled by a; split band 45 (seeFig. 7), which latter is provided at its separated ends withtwo voutwardly turned lugs 46 and 47. The band is secured to a boX or casing 48, which latter is keyed to the shaft 41, the band being adable set screw 4 9 engaging one lug 46, `and a band-actuating pin k50 engaging the other lug 47. The pin 50 is mounted toturn in the and presents a flat face 52 to the outer edge vjustably held therein by means of an adjustwalls of a pocket 51 formed in lsaid casing to draw the separated ends of the yband to- .s gether and grip the drum member 44; tliereq` by clutching the casing 48 to the gear member 39 and operatively connecting the counter-shaft 41' tothe transmissioncshaft 6.

To turn theA actuating pin 50,v the latter is provided with the curved arm 53 which lies down and over the hub 54 of the casing,

lbeingpressed inwardly by means ofthe spiral spring 55. The arm 53', however, may be swung outwardly to turn the lpin by means of the wedge-shaped sleeve 56 slidable ylengthwise the. hub 54. The sleeve is provided with a circumferential groove 57 with which engages a yoke-shaped arm 58 (FigQ4), saidarm being attached to the slide rod 59. The end of the slide rod (see Fig. 5) is secured to a hand 'lever 60 pivoted at 61'upon the frame, so that, by moving the hand lever, the gear member 39 ymay be clutched to or unclutched from the countershaft 41. The remaining vgear member 40 is provided with clutching devices similar in construction to those already described, and its wedge-shaped controlling. sleeve 62 is also adaptedto be moved by an arm 68, the latter alsor connected to the slide rod 59, so that vmovement of the latter will serve to move both sleeves simultaneously. Preferably the sliderocl and handle are so arranged that they may be movedto any one of three posiposite direction and a third or intermediate position for securing inactionor rest.

Referring now 'to the mechanism for varying the speed of the driving sprocket wheel 37 for the tool feed, the latter is journaled on a stud shaft 64 and has formed integrally vtherewith the beveled gear 65 which meshes which may be clutched to or unclutched from oppositely driven driving members 70 and 71, respectively, by devices of a gen-l the truck driving members.

' riesame;z

erally similar construction Vto those/f previously described.

f The driving member 70 is provided with a spur gear 72 which meshes with spur teeth cut upon the gear or truck-driving member 39, while the tool' feed driving member 71 is provided with spur teeth 73 which mesh with similar teeth cut on the truckdriving member 40. Fromthis it follows that the driving members 70 and 71 are con stantly driven in opposite directions so that,A

through a like actuating pin and band the` tool feed driving member 71 may be clamped to the drum 69 to turn the sprocket wheel in an opposite direction by sliding movement ofthe controlling sleeve 78. To shift the controlling sleeves simultaneously in either directionthe sleeve 76 (seeliig.y et) is engaged by the arm 79 and the sleeve 78 by the arm 80, both arms being attached to the slide rod 8l adapted to be shifted by the hand lever 82, so that, through the movement of thelatter by the connections described the feed screw may be turned in one direction or the other, or allowed toy remain stationary.

It will be'noted that the power-transmis sion gearing described provides two sets or pairs of driving members, one for thetruck and the other for the tool feed, the members of each pair being driven in opposite directions whereby any one may beclutched to its respective driven shaft independently, whereby either tool feed driving member may be rendered operative for feeding the tool irrespective of the operative relation of lt therefore follows that the tool feed may be operated under power and in either direction whether the truck be in motion or at rest and irrespective of the direction in which it may be moving.

In adjusting: the standard to different inclinations, the position of the `driving sprocket wheel 37 should also be adjusted to conform thereto and for this purpose the shaft 64 onk which the sprocket wheel is journaled ismounted in an adjustable frame or swinging quadrant 83, the latter. adapted to be adjustably swung about the driving shaft 7 to keep the required relation between the beveled gears and 66, while, at the same time, conforming to the inclination of the driving sprocket chain 36.

The quadrant 83 isprovided with a split hanger bracket 84 by which it issecured :to

swing about the shaft 7, such bracket also affordinga support 85 for one end ofthe sprocket wheel shaft 64, the opposite end thereof being supported in a bracket 86. The quadrant 83 is provided with segmental guiding edges 87 (Fig. 2), the sides of which areembraeed by the walls 88 of a clamping frame 89 which, after the quadranthas been adjusted to the required position, is clampedl tightlv about the latter to holdit liXedly in place.

The clamping` frame is secured to the front wall 9() ofthe carriageframe by bolts 91 and comprises two projecting segmental ears 'whichpresent the walls 88 to embrace the quadrant, these beingconnected at their lower ends by theclamping bolt 92, and also the connecting portion 93 partly split at. 9st.y The connecting portion 93 unites the upper ends of the segmental ears and is adapted to be tightly clamped together by the clamping bolt 95.

The quadrant is provided with a pin 96 which abuts against a. lug 97 on the frame lv to limit the movement of the quadrant be-k yond a position `corresponding to an up* right positionk of the standard, such pin alsolimiting the movement in the opposite,

direction bv engagement with the clamping bolt 92. lVhen the standard is tipped back the bolts 92 and 95 may be loosened and the quadrant tipped with it to any desired position, after which `the clamping frame is again tightened by the clamping bolts 92 and 95.

Asrepresented in1Fig. 3, the standard is provided with a laterally adjustable guide roll or sheave 98 engaging one run of the;

sprocket chain, so that ythe latter may be guided and kept taut to the sprocket wheel 35 in whatever position on the truck the standard may be adjusted.

Since the quadrant and the clamping frame present coperating extended segmental clamping and holding portions symmetrically arranged with reference to the axis of the sprocket wheel and on either side thereof, the sprocket wheel is securely held in its adjusted positionr against any lateral pull of the sprocket chain.
